In 2016,Chen, Yan-yan; Chen, Zhen-yu; Zhang, Niu-niu; Chen, Jia-hua; Zhang, Xue-jing; Yan, Ming published 《Intramolecular Addition of Triarylmethanes to Alkynes Promoted by KOtBu/DMF: A Synthetic Approach to Indene Derivatives》.European Journal of Organic Chemistry published the findings.Application In Synthesis of 1-Bromo-2-isopropylbenzene The information in the text is summarized as follows:
A method for the intramol. addition of triarylmethanes to alkynes has been developed. The reaction was efficiently promoted by KOtBu/DMF without any transition-metal catalyst. A variety of indene derivatives, e.g., I, were prepared in moderate to good yields. A cascade cyclization of 2-alkyl-substituted substrates at elevated reaction temperature gave bicyclic indene derivatives The reaction is proposed to proceed through the generation of a triphenylmethyl radical. In the experimental materials used by the author, we found 1-Bromo-2-isopropylbenzene(cas: 7073-94-1Application In Synthesis of 1-Bromo-2-isopropylbenzene)
1-Bromo-2-isopropylbenzene(cas: 7073-94-1) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. Application In Synthesis of 1-Bromo-2-isopropylbenzene Alkyl bromides are mainly used as alkylating agents and also find application as a solvent to extract oil from seeds and wool.
